non turbos dont require rising rate regulators . weather they change them im unsure.
factory rails are fine unless your looking for quite large power .
youll need turbo regulators unless subaru just put rising rate ones in everything. I find it hard to believe they made different size rails and that would be an uneconomical move by subaru.
yea bro thats right. flat4 got sas to put turbo headers into his tsr.
if I remember right it had to be changed. there was somthing else tho might have been the crossmember or the radiator.
but the water pump deff had to be changed . the way the pipe directed from the thermostat to the rad went straight into the headers. so ya have you pull cam belt ect

I wouldn\'t be trusting that at all . the copper washer is the seal.
